A055 Amend Canons IV.2, IV.11.1, and IV.17.2.e regarding Investigators

This change cleans up inconsistencies in Canon IV.2 regarding the appointment and role of Investigators. It removes a few portions of the definition of Investigators in Canon IV.2 and places them in the procedural portion of the canons and brings the canons in line with current practice in the case of a Title IV process involving a bishop.
